Cytoscape: An Open Source Platform for Complex-Network Analysis and Visualization Le New-York Times veut prévoir ses désabonnements 01net. le 13/02/14 à 16h37 © hackNY.org Chris Wiggins avec des étudiants en 2011. Il s’appelle Chris Wiggins et c’est une star des algorithmes. Les grands journaux américains s'intéressent aux algorithmes Sur son compte Google +, il résume ainsi son parcours : « Mathématicien appliqué avec un doctorat en physique théorique sur l'apprentissage automatique pour la biologie computationnelle. » Alors, quel rapport entre les mathématiques appliquées à la biologie et le New-York Times ? Le vénérable journal serait désireux d’enrayer l’effritement de son vivier de lecteurs et souhaiterait identifier ceux qui pourraient s’apprêter à se désabonner... pour les convaincre à temps de ne pas le faire ! A charge pour Wiggins de développer des algorithmes dans ce but. Lire aussi :

MAGE software Mage is a 3D vector display program which shows "kinemage" graphics. Used in both teaching and research, in applications ranging from estuary ecology to X-ray crystallography model quality assessments, Mage displays the 3D relationships between data in an interactive environment which facilitates both open-ended exploration and structured presentation. It includes many tools for on-screen measurement, construction, and editing of the display objects; it can write either kinemage output or various types of 2D image output. Mage is available for several popular platforms. The windows download is as the exe (not compressed, or otherwise protected), because we still encounter some Windows systems without a default compression/archival utility such as WinZIP. (1)Icon files are available: mageicon.win.ico.zip (0.4KB, for Windows), mageicon.png.zip (2KB, for Linux), mageosx.icns.zip (8KB, for MacOSX) (2)MacOSX Mage is an unix program, not a native OSX program.

Computer science: The learning machines Three years ago, researchers at the secretive Google X lab in Mountain View, California, extracted some 10 million still images from YouTube videos and fed them into Google Brain — a network of 1,000 computers programmed to soak up the world much as a human toddler does. After three days looking for recurring patterns, Google Brain decided, all on its own, that there were certain repeating categories it could identify: human faces, human bodies and … cats1. Google Brain's discovery that the Internet is full of cat videos provoked a flurry of jokes from journalists. But it was also a landmark in the resurgence of deep learning: a three-decade-old technique in which massive amounts of data and processing power help computers to crack messy problems that humans solve almost intuitively, from recognizing faces to understanding language. Deep learning itself is a revival of an even older idea for computing: neural networks. “AI has gone from failure to failure, with bits of progress.

Resources LOOK INTO Equity- Crowdfunding In her book Cash From the Crowd, Sally Outlaw, founder and CEO of crowdfunding website peerbackers, reveals the secrets of funding your business with help from colleagues, peers, family, friends and even perfect strangers through a crowdfunding campaign. In this edited excerpt, the author provides information on the new equity-crowdfunding model that was authorized by the JOBS Act of 2012. Until now, crowdfunding has come from backers who donate money with no expectation of a financial return, but that's about to change. The JOBS Act, which offers the first changes to securities law in more than 80 years, enables a new equity-crowdfunding model that allows backers to buy shares in posted ventures. Entrepreneurs who list on equity-crowdfunding platforms will have an opportunity to raise serious capital and must also manage new expectations, responsibilities and obligations to regulators and shareholders.
